What is a scalar and vector quantity ??​

the answer below me is correct

Explanation:

Scalar quantities

Scalar quantities only have magnitude (size).

For example, 11 m and 15 ms-1 are both scalar quantities.

Scalar quantities include:

distance

speed

time

power

energy

Scalar quantities change when their magnitude changes.

Vector quantities

Vector quantities have both magnitude and direction. For example, 11 m east and 15 ms-1 at 30° to the horizontal are both vector quantities.

Vector qualities include:

displacement

velocity

acceleration

force

weight

momentum

Vector quantities change when:

their magnitude changes

their direction changes

their magnitude and direction both change

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.
